IMPROVEMENT IN CAR BRAKES AND STARTERS.

Specification forming part of Letters Patent No. 125,049, dated March26, 187

Specitication describing certain Improve wments in (Jar Brakes andStarters, invented by CHARLES M. HINCKLEY, of Boston, in the county ofSui'olk and State of Massachusetts.

This invention is an improvement upon the car brake and starter inventedby David M. Moore, and upon which he obtained a patent dated July 20,1869, and numbered 92,869. My invention relates to an improved method ofshipping and unshipping the gear.

ln the accompanying drawing, Figure l is a plan ofthe under side of acar embodying my invention-no car-wheels are shown, as they are not apart of my improvement. Fig. 2 is an elevation, showingthe platform,dash-board, &c., with a piece broken out of the latter to show thegearing, Sac., under the car to better advantage. Fig. 3 is a plan ofthedrum. Fig. 4 is an elevation of the same.

Similar letters of reference indicate corresponding parts.

al a2 are two common varieties of brakehandles. b is the dashboard. c care cranks or levers, to which are attached the wires or chains d d. d dare chains, cords, rods, or their equivalents, ruiming from the levers cc to the levers e e. e e are levers or cranks bent down into rods ff,which lie in slots in the Wheels g g. g g are the geared wheels, shownin Moores patent, above referred to. his the Wheel, shown in Moorespatent, into which the wheels g g mesh. k is the drum, as shown in saidpatent. ma are flanges extending from the drum k. o is a slot or cut inthe drum k, to allow room for the rst link of the chain. p is a shortrod or bridge running across the slot o, in which or around which isplaced the first link of the chain.O s is the rst link of the chain.

To place the wheels g gin or out of gear with the wheel h, a partialturn of one of the brake-handles is all sufficient. These handles aremuch more convenient, and take less room in operating than the longlevers shown in Moores patent. In place ot' stift' shippers (which mustbe made ci' such strength and size as to be too heavy for use) Isubstitute cords, chains, ortheir equivalents, in connection with thecranks c c and bent levers e f. drawing motion, and requires but littlestrength and no stiii'ness in the shippers d i.` The bent levers ef movethe wheels g g perfectly and easily. Handles may be placed at each endof the car.

In connection with my drum 7c I have two flanges, m mboth of which areattached to and a part of the drum. Moore has no [lange upon the drumitself, unless a slight rim at the top might be termed a flange. Ipropose to make my anges as large as possible Withoutinterfering withthe gear, so that there shall be no danger of the chain slipping off thedrum. The slot, in which the link s is placed, may be made deeper, ifdesired, and the rod or bridge p will, probably, be set further in theslot 0. will be no obstacle to the smooth winding ot' the. chain. Thedrum will be made as thin as practicable, using as little stock aspossible, thus giving opportunity for wide flanges.

Ths invention Works finely, practically, and is, in my opinion,avaluable improvement upon Moores patent, above referred to.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- The arrangement of the cranks or levers cc, shippers d d, and bent levers e f c f,.when placed in combinationwith the geared Wheels g g, and playing in slots or their equivalentsupon the same, substantially as described, and for the purposes setforth above.
